1末次盛冰期以来菲律宾南部气候变化的孢粉记录显示文摘通过对位于西太平洋暖池区的菲律宾南部深海钻孔MD06-3075上半部分的孢粉分析,结合氧同位素记录,得知冰盛期时由于温度的下降,该区热带高山雨林向低海拔地区下移,在深海沉积中记录到了这一类型花粉的增加;而到全新世时植被类型以热带低地雨林为主,并且红树林广泛发育.红树林和高山雨林的变化,分别指示了海平面的上升和温度的增加,而其他的草本、蕨类等变化则显示冰盛期时湿度比现在要略干.在全新世中后期红树林明显退缩表明全新世时期气候发生变化,主要表现为影响红树林发育的河流径流量有所下降,同时喜湿且主要依靠河流搬运的蕨类孢子减少,也说明河流径流量下降.这些变化可能是受东亚季风强弱变化控制的结果,也可能和ENSO的变化有关联.边叶萍 翦知湣 翁成郁 KUHNT Wolfgang BOLLIET Timothe HOLBOURN Ann 2011科学通报2011,56,19:5
2东西特提斯晚白垩世深水底栖有孔虫生物相和岩相(英文)显示文摘白垩纪深水古海洋学研究仍处于早期发展阶段,一方面是由于来自钙质底栖有孔虫的稳定同位素和地球化学数据的缺乏,其原因在于白垩纪高碳酸盐补偿深度;另一方面在于深水有机质胶结有孔虫示踪古海洋还没有充分发展起来。深海环境深水胶结有孔虫的分布主要取决于碳酸盐可利用状况、原始生产的输入通量、深水交换、环境波动(深海洋流、浊流和快速沉积事件)和底层沉积类型,因此对于重建深海环境具有非常巨大的潜力。东、西特提斯Campanian Maastrichtian深水底栖有孔虫组合的统计分析揭示出6个生物相,代表着明显不同的沉积环境。包括:深海红色泥岩与矮小深海生物组合(生物相1);红色深海泥灰岩(“Couches Rouges”相),含钙质胶结有孔虫组合(生物相3);深水远洋灰岩(“Scaglia Rossa”相),含易碎的Rhizammina组合(生物相2);绿色灰色半远洋泥灰岩,含适应高输出通量生物组合(生物相4);半远洋泥岩和粉砂岩,含Aschemocella Nothia 组合(生物相5);陆源浊积层序,含“复理石型”Rhabdammina组合(生物相6)。Campanian Maastrichtian红色氧化深水环境动物组合与现今深海类似,而白垩纪贫氧深海环境胶结组合在现今无法找到相类似物。随着古生态信息的增加和数据库的扩展,深水胶结有孔虫有望成为揭示古海洋条件的重要工具,尤?Wolfgang KUHNT Ann HOLBOURN 2005地学前缘2005,12,2:5
321 ka以来帝汶海区钻孔堆叠记录的古海洋学意义显示文摘印尼穿越流是连接西太平洋和印度洋的唯一载体,与东亚季风和ENSO活动密切相关。帝汶海区是印尼穿越流的主要出口之一,该区不同钻孔末次冰期以来的古海洋学记录显示在长时间尺度上变化存在着很高的相似性。为了捕捉出口处印尼穿越流的平均信号,本研究将这些记录进行堆叠,并与其他海区的钻孔记录进行对比,探讨印尼穿越流对东亚季风和ENSO活动的响应。总体上,堆叠记录较为精准地复制了各个钻孔记录的信息。帝汶海区表层海水温度堆叠记录与其他海区钻孔记录对比显示末次冰期至12~6 ka期间帝汶海可能位于暖池范围内,而晚全新世时位于暖池的边缘;温跃层深度、海水温度和盐度堆叠记录揭示自末次冰期以来印尼穿越流温跃层流呈现逐渐强化的趋势。结合现代水文资料和堆叠记录与其他古海洋古气候记录的对比等,本文推测了不同时期ENSO的冷暖期状态以及东亚季风对印尼穿越流的影响方式和过程。徐建 可菲 Wolfgang Kuhnt Ann Holbourn 张鹏 崔瑞 刘恒 孙金梁 2020第四纪研究2020,40,6:4
4A palynological and palaeoclimatological record from the southern Philippines since the Last Glacial Maximum显示文摘A palynological analysis of a marine sediment core in the southern Philippines,provides a detailed regional vegetation and climate history for the West Pacific Warm Pool(WPWP)since the Last Glacial Maximum(LGM).Chronology was determined by a detailed oxygen isotope record.A higher representation of pollen from tropical upper montane rainforest during the LGM indicate that this forest type moved down along elevation,probabaly due to the lowered temperature.During the last deglaciation and the early Holocene,mangroves were more expanded and tropical mid and upper montane rainforests were restricted,suggesting a rising sea-level and temperature increase.Herbaceous pollen and pteridophyte spore records indicate a much drier condition during the LGM than the Holocene.Mangrove development is controlled by conditions at the river mouth influenced by river discharge.Pteridophyte spores are abundant in wet conditions and are mainly transported by rivers.During the mid-Holocene,the reduction in mangrove pollen and pteridophyte spore appears to be a result of climate change:mainly decrease in river discharge.This may have been affected by the decreasing intensity of the Southeast Asian Monsoon,and the increasing frequency and intensity of warm ENSO events,El Ni?o,in this region.BIAN YePing JIAN ZhiMin WENG ChengYu KUHNT Wolfgang BOLLIET Timothe HOLBOURN Ann 2011Chinese Science Bulletin2011,56,22:3
